    Fractional flow reserve (FFR)-based therapy in patients presenting with acute coronary syndrome: Current data and everyday practice.
    Cardiol J 2017 27;24(4):426-435. Epub 2017 Jun 27.
    First Department of Cardiology, Medical University of Gdansk, Debinki 7, 80-952, Gdansk, Poland.
    Fractional flow reserve (FFR) is an evidence-based diagnostic tool of physiological significance of coronary artery stenosis in patients with stable coronary artery disease (CAD). Due to microvascular dysfunction in acute coronary syndrome (ACS), information obtained from FFR assessment could be less reliable and, thus, its clinical role remains controversial. Indeed, results of currently published studies are essentially discrepant. Read More

    Echocardiographic evaluation of right ventricular systolic function: The traditional and innovative approach.
    Cardiol J 2017 May 12. Epub 2017 May 12.
    Department of Cardiology, Hospital of Saint Wojciech, Copernicus.
    Estimation of right ventricular (RV) performance still remains technically challenging due to its anatomical and functional distinctiveness. The current guidelines for the echocardiographic quantification of RV function recommend using multiple indices to describe the RV in a thorough and comprehensive manner, such as RV index of myocardial performance, tricuspid annular plane systolic excursion, fractional area change, Doppler tissue imaging-derived tricuspid lateral annular systolic velocity (S'-wave), three-dimensional RV ejection fraction (3D RVEF), longitudinal strain (RVLS)/strain rate by speckle-tracking echocardiography (STE). Among these, the last one mentioned here is an innovative and a particularly promising tool that yields more precise information about complex regional and global RV mechanics. Read More
